. noon-Loci: STRIKER PLATE.

Application filed March s, 1926. se ial 1%. 9 5, 14.

i The present invention relates to door lock striker plates, and has for its object to provide a device of this character Which embodies novel features of construction, whereby the part which is engaged by the latch bolt is movably mounted so thatit can move with the latch bolt when thereis relativemovement between the parts, thereby avoid ing wear between theparts. The door lock striker plate of this inventionisparticularly well adapted for use upon automobiles or other vehicles where the doors are subjected to constant jarring and vibration when the vehicle is in use. Undersuch conditions it will be readily understood that where there is the slightest looseness in the door the con- 1 stant movement of the latch bolt against the striker plate will cause the parts to wear very rapidly, thereby increasing the looseness and causing more noise and rattle.

With the present invention the foregolng objection is overcome by providing the door lock striker plate with a bearing'platewhich is mounted thereon in a novel manner so that it will engage the latch bolt of the door and move therewith if there is any relative movement betweenthe .door, and doorjamb,,

thereby preventing the rapid wear of the latch bolt and striker plate which would otherwise'take place. a

While one particular embodiment of the invention is shown and described in this ap: plication for illustrative purposes, it will be understood that many modifications" andv changes can be made inthe details of con,- struction without departing from the spirit of the invention. 7 I

For a full understanding of the invention reference is to be had to the following description and accompanying drawings in which,

striker plate which isconstructed Figure 1 is a rear view of a door lock ance with the invention.

Figure 2 is a longitudinal SGCtlQDfllVlGW through the same on the line 2-2 of Fig ure 1.

Figure 3 is a sectional view taken on the line 33 of Figure 2. I.

Figure 4 is a detail perspective v1ew of the body portion of the striker plate.

Figure 5 is a detail perspective v1ew of the retainer plate which is applied to the hack of the striker plate, and

in accordably mounted bearing,while Figure? isa top plan view thereof. Corresponding and like parts are referred to in the following descriptioniand indicated Figure 6-is a side elevation of the slidon allof the views of the drawing like reference characters. J

Referring to the drawings, the numeral li' -des1gnates the body portion of thestriker plate which is provided with the usual" wedge shaped entering surface. 2 against which-the latch bolt 80f the door engageswhenthe door is beingclosed. Theinner end of the latch-plate isrecessed at the back thereof to provide a chamber 4-. The back of the chain ber isclosed by a retainer plate 5 which may be held remov-ably in position by suitable fastening members, such as the screws. .6. If desired the back of the striker plate may be reoessedjto receivethe retainer plate. The

innerfend of the chamber 4 provides ashoulder which l1as-a 'substantially spaced and parallel relation. to. the end .of the striker plate- A hard metal facing plate 7 is shown asapplied to this shoulder."- r

' A bearing member8 issli dably mountedwithin this chamben "As shownon the drawing the bearing member has a channel shaped formation, the side flanges project- 111g within the chamber .4 and receivingjantifriction rollers 9 between the same." These antifriction rollers 9 are interposed between.

the bearing plate: and theshoulder atthe inner end of the chamber and the bearing plate is adapted to ride- .freely back. and forth upon therollers; The inner ed-geof the r-earfiange of the channel vshaped bearing plate 8 is provi'dedqwith an-outwardly deflected lip 10. which is received within a corresponding slot 11in the retainer plate. 5. 1

This lip thus serves to preve'nt'displacement of the bearingplate from the striker plate,

although it slides freely in the slot 11 as .thev i bearing plate rides backand forth-'onfthe ing plate and the ends of the chamber.

When the door is completely olosedthe latch bolt 3 thereof is projected ever the bearing.

late 8 andengages the same as shown by igure 2. The latch bolt may engage the bearing plate with considerable force, al-

though if there is any relative movement between the door and door jamb, the bearing plate will remain in engagement with the door lock and ride freely back and forth on the rollers 9. The movement-of the bearing plate 8 on the anti-frictionrollers 9 is not accompanied by any-Wear and pre vents the door latch bolt from outtinginto the striker plate as it would otherwiseldo. The bearing plate 8 may be somounted that it will have a slight tilting movement and 1 can. accommodate itself to the face: ofthe latch bolt 3. The outer'surface of thestriker plate is shown as provided with the usual safety catch 12 which prevents the door from opening and causing an accident in the event it should not be securely closed.

Having thus tlQSCllbBCl my lnventlon what I'claim as new and desire to secure by Let- -ters Patent is,

1. A door lock striker plate including a body portion, and a bearing member adapted to engage the latch bolt and freely movable on thevbody portion while so engaged in a direction substantially parallel. to the adja- .cent edge of the door opening. and at right angles to the direction of-movement of the v latch bolt when engaging the same.

2. door lock strikerplate including a body portion, a bearing member movably mounted thereon andarranged. for engagementwith the latch .boltv of the door, and anti-friction rollers for the bearing member.

3. A- door lock striker plate including a body'portion having a pocket in the rear end thereof, a bearing member slidably mounted in the pocket and extending through the 'Inouth thereof for engagement with thelatch bolt of a door, and retaining means for bolding the bearlng member in position, the direction of movement of the bearing member being at right angles to the direction of movement of the latch bolt as' it engages therewith.

' 4. A door lock striker plate including a body portion having ahpocket in the rear end thereof, a channel shaped bearing member slidably IHOLlIltQdWltlllIltllG pocket and extending through the. mouth thereof for en gagement with the latch bolt of a door, and. anti-friction rollers arranged between thev fia'ngesof the channel shaped bearing member.
